A star in the constellation of Cygnus about 1,300 light-years away, said to have an alien civilization’s megastructure upon it, is giving off some strange light patterns again.The mysterious dimming and flickering of the star, first discovered in 2011, means something is passing in front of it. A range of theories have been put forward for this odd, light-flickering behavior, including one hypothesis which suggests an alien megastructure may have been built around the star to harvest its energy.http://themindunleashed.com/2017/05/telescopes-trained-alien-megastructure-star-previously-dismissed-nasa.html
